What are the key features of MCR03EZPFX5102?
- 51 kΩ resistance with ±1% tolerance provides precise resistor values for feedback networks and signal conditioning circuits
- 0.1 W power rating in compact 0603 (1.6 mm × 0.8 mm) package suits high-density SMT designs with minimal board space
- ±100 ppm/°C temperature coefficient ensures stable resistance across industrial temperature ranges for accurate analog circuits
What is MCR03EZPFX5102 used for?
The MCR03EZPFX5102 is widely used in voltage divider networks, feedback resistor chains for op-amp circuits, and pull-up or pull-down resistors in digital logic designs where a precise 51 kΩ value in a small 0603 footprint is required. Its ±1% tolerance and ±100 ppm/°C TCR make it suitable for signal conditioning and gain-setting applications in sensor interfaces and instrumentation. The RoHS-compliant, lead-free construction suits consumer electronics, automotive support electronics, and industrial PCBs manufactured under environmental regulations.

Frequently Asked Questions
What is the resistance value and tolerance of the MCR03EZPFX5102 and what package size is it?
The MCR03EZPFX5102 has a resistance value of 51 kΩ with a ±1% tolerance, housed in a 0603 SMT package measuring 1.6 mm in length and 0.45 mm in height. The ±1% tolerance ensures that the actual resistance remains within 510 Ω of the nominal value, making it accurate enough for precision voltage dividers and feedback networks in analog circuit design.
How does the ±100 ppm/°C TCR of the MCR03EZPFX5102 affect performance in temperature-varying environments?
The ±100 ppm/°C temperature coefficient of resistance (TCR) means that for every 1°C change in temperature, the resistance shifts by at most 100 parts per million of the 51 kΩ nominal value, which is 5.1 Ω per degree. Over a 100°C operating range from -25°C to 75°C, the worst-case drift is 510 Ω or approximately 1%, well-suited for gain-setting and filter applications where temperature stability is important but not ultra-precision requirements below 50 ppm/°C.
When should MCR03EZPFX5102 be chosen over a 0402 resistor of the same value for a compact PCB layout?
The 0603 package of the MCR03EZPFX5102, at 1.6 mm × 0.8 mm, should be chosen over 0402 when manual rework or inspection is needed, as the larger pads are easier to handle with standard tweezers and soldering tools. For the same 51 kΩ value, the 0603 also handles 0.1 W power dissipation, compared to 0.0625 W typically rated for 0402 parts, providing more headroom in circuits with elevated ambient temperatures above 70°C. Use 0402 only when board space below 1 mm² per resistor is the overriding constraint.
